Now the exception is called a first chance exception.

This exception is also used by the Apex Flex Queue methods and is thrown if you attempt to access a job } } catch (const BaseException& e) { std::cout << "Second catch block: " << e.what() << std::endl; // Output ==> Second catch block: BaseException } return 0; } If you are sure that you are not going to do anything to change the exception (like add information or modify the message), catching by const reference allows the compiler to make I had initially misread the question, updated to add some value. Willy Zhang's answer is perfect. Update: Yes, [code py]except:[/code] would handle all exceptions, whereas [code py]except Exception:[/code] would handle only exceptions derived f @MaggieYing: Exception is a subclass of BaseException, but it is not the only such subclass. There are other subclasses too, see the inheritance diagram in the docs; those other exceptions are not really errors but signals that you usually would not catch. – Martijn Pieters ♦ Apr 19 '18 at 6:45 Get code examples like "python baseexception vs exception" instantly right from your google search results with the Grepper Chrome Extension.

I get "TypeError: exceptions must derive from BaseException" even though I did define it Python according to python documents, Exception is derived from BaseExceptions and I should use it for user defined exceptions. so I have: When exception occurs, it is checked to match the exception type in except clause. If match is found then handler for the matching case is executed. Also note that in last except clause ExceptionType is omitted. If exception does not match any exception type before the last except clause, then the handler for last except clause is executed. } } catch (const BaseException& e) { std::cout << "Second catch block: " << e.what() << std::endl; // Output ==> Second catch block: BaseException } return 0; } If you are sure that you are not going to do anything to change the exception (like add information or modify the message), catching by const reference allows the compiler to make This exception is thrown if you try to access items that are outside the bounds of a list.
